enrichment often occurs at depth while lower gold grades occur in the system’s upper levels. An example of the potential for grade to increase at depth is found 9 km southeast of Cerro Caliche at the Mercedes Mine, which is extracting gold from an LS epithermal deposit that is an extension of the same mineralization system as Cerro Caliche

Native gold, R30017. Source: Geoscience Australia. Gold, like iron, copper, lead and tin is a metal. Gold is the only yellow metal and is chemically very stable. It does not readily combine with other substances and, therefore, does not corrode or tarnish. Because of this property, it is almost always found in nature as pure gold.

In gold plants, for example, a number of gravity devices, old and new, are being used to recover relatively coarse gold. Over the past few years gravity separators that take advantage of differential specific gravities in a high-gradient centrifugal force field (e.g., Knelson and Falcon separators) have been used successfully for gold. Older devices (such as spirals on which the centrifugal

Is gold an ore? On Earth, gold is found in ores in rock formed from the Precambrian time onward. It most often occurs as a native metal, typically in a metal solid solution with silver (i.e. as a gold/silver alloy). How can we extract metals from their ores? There are 3 main methods of extracting metals from their ore.
